Application filed April &,

' To all whom may i Be it known that. we, (1) Fnarn; E. Mc- CAnn' and (2) MICHAEL L. Rosnn'mo, citizens of the United States, residing at (1) Oha Falls, (2) Cleveland,.in the county of .ahoga and State of Ohio, have invented a certainnew; and useful Improvement 'in.

Bungs and Bung Bushings, of which the following is'a full, clear, and exact description, reference being bad to the accompanying drawings.

This invention relates to sheet-metal barrels or containers, or to containers involving sheet metal parts togwhich the bung bushing is attached, and it has particular reference to a novel formof bushing and a unique means for attaching the -same to the sheet metal parts in a manner similar to, but constituting an improvement over that described in an application, Serial No; 434,089, filed December 30, 1920, vby Frank E. McOabe. The principal object of the present invention is to provide a simple and inexpensive 26 construction through which the bungbushing may be attached quickly and in a particularly convenient manner, the same representing a material saving of time, labor andexpense over the methods at present 30 em loyed.

other object is to provide abun bush-.

ing of the aforesaid character whic shall includemeansfor draining the entire contents of the container even including the small quantity usually retained by reason of a portion of th; bung flange projecting into the interior 0 the containe A still further object is to provide a bung P bushing and plug thereforv which shall in- 40 elude means for carrying a faucet or other suitable dispensing device on the interior of the container and which dispensing device may be easily removed and attached to the exterior sideof-said plug .when ready for use, thereby eliminating the need of a se arate attaching bushin in the container.

ith these and other 0 jects in view the invention consists in the various novel features of construction and combination of 59 parts described hereinafter and pointed out 1n the claims. 7 e

In the accompanying drawing wherein we have shown the'present preferredembodimeat or our invention, Fig. l is a vertical 1921. Serial No. 458,497.

sectional view through the bung bushing and plug illustrating the same attached to' a wall of'a sheet metal container; Fig. 2 is an inside view of the bushin applied to the wall of the container; am? Fig. dis a perspective view of the bushing, a section of the container wall, and plug, in separated condition. i

The sheet metal wall 1 of the container is provided with a hung hole 2, the sheet metal defining the periphery thereof beingturned inwardly to form a shallow flange or lip 3,

form and is provided with a flange 6.

fi'will engage the wall of the container and the flange or lip '3 will fit within said counterbore. The cylindrical body portion of the bushing is provided with a plurality of notches 8 which are adapted to register with the lugs 4. These notches extend from the .inner edge of the body portion which projects within the container, to .within.- a short distance of the flange 6 to'definc shoulders 9, and on the inner side said shoulders are recessed as indicated at 10 to permit' the lugs 4 to lie below the surface of the internal thread 11 within said body portion.

The surface of the flange 6 which engages the sheet metal wall of the container is formed with a plurality o'f radial grooves 12 so that the entire contents of the container may be easily drained.

In attaching the bung bushing to the sheet'metal wall, the bushing is positioned, I

over the opening 2 so that the lugs 4 will register with the notches 8. The flange 6. wi l engage the sheet metal wall of the container and the lip-3' will project within the counterbore 7. The lugs 4 are then bent around the shoulders 9 as shown in Fig. 1, thereby securing the bushing to the container in asimple and convenient manner which may machine. k I I The filling plug 14 is externally threaded to engage the internal thread 11 and is provided with a head 15 which may be suitably shaped to receive a wrench. A washer16 is interposed between the head 15 and the be accomplished manually or by outer wall of the conwiner to prevent.l-

age. We preferably form the plug it with a straight threaded bore 17 extending therethrough and close said bore .on the exterior side of the plug with a small taper threaded plug 18 and utilize theremainder of said hence avoid the expense of providing two bushings in the container and also reduce the possibilities of leakage which is apt to occur at the bushings. -'Ihe small plug 18 might be dispensed with as the faucet 19 could be closed tightly and thereby prevent leakage. However, we prefer to use the plug 18 as a safeguard against leakage of the faucet and also to keep foreign matter from entering therein during shipment.

Having thus described our invention, what we claim is 1. In a construction of the character set forth, the combination of a sheet metal wall having an opening and a plurality of lugs projecting from the edge of the opening, and a bushing applied to the Wall in register with the opening and having notches therein for receiving said lugs, said notches terminating short of said well to define shoulders, said lugs being offset laterally in said notches for securing said bushing in place.

2. In a construction of the character set forth,the combination of a' sheet metal wall. having an opening, a lip projecting in- 1 wardly about said opening, a plurality of lugs extending from the lip, and a bushing adapted to receive the .lip and having notches therein for receiving said lugs, said notches terminating short of said wall to ,define shoulders, said lugs being offset laterally in said notches for securing said bushing in place.

3. In a construction of the character set.

forth, the combination ofa sheet metal wall having an opening surrounded by an inwardly directed lip from the edge of which lddltldii 18 project a pluralit of lugs, a cylindrical bushing having a auge at one end arranged to fit against said wall and eounterbored to receive said lip, the diameter of the counterbore being greater than .the internal diameter of the bushing, a plurality of notches formed in said cylindrical bushing and tering notches therein terminating short of said wall to define shoulders, and said lugs being ofiset laterally over said shoulders to secure said bushing in place.

5. In a construction of the character set forth, the combination of a sheet metal wall having an opening and a plurality of lugs projecting from the edge of the opening, a cylindrical bushing applied to the. wall in register with the opening, said bushing having notches terminating short-of said wall to define shoulders, the inner surface of said shoulders being recessed to receive said lugs and said lugs being offset laterally over said shoulders to secure said bushing in place.

6. In a construction of the character set forth, the combination of a sheet metal wall having an opening, of a bushing secured to said wall in register with said opening, and a plurality of recesses formed between said bushing and said wall and communicating with said opening and the interior of the container.

7. In a construction of the character set forth, the combination of a sheet'metal wall having an opening, of a bushing secured to said wall in register with said opening and having a flange contacting with saidwall and bordering said opening, and .a plurality of recesses formed in the contacting face of said flange and communicating with said opening and theinterior of the container.

In testimony whereof, we hereunto affix our signatures.
